HIGH POWER ROUTER TEST REPORT HIGH POWER user s manual Quick Install Guide Cable DC Power Adapter Wireless Local Area Network also known as WLAN Wireless LAN has become a popular network mode with more and more users It is quite convenient for users since there is no need to wire When we use it sometimes we may find that the wireless signal is unstable data transmission speeds may slow down A router of high quality should be equipped with the following functions 1 Reasonable design of basic hardware safe reliable low power consumption long life span 2 Stable and applicable software which provides value added upgrade service 3 Long distance stable transmission of wireless signal requires broad bandwidth and wide coverage Among them the third point is the problem of industry because the RF recognized the size of wireless transmission power and the transmission distance is proportional to relationship but vast quantities of power radiation on human safety is harmful and therefore must enhance wireless signals the only way is to improved antenna enhance antenna gain reducing the wireless signals loss in transit and then combining of mainboard which all improve spectrum efficiently BL WHO1 use a new type of high power gain antenna aperture type phased antenna this technology has in patent application and itis anticipated to get patent certificate in June2012 http www hlktech com First we mak
